A fascinating account of how radical researchers have used experiments to overturn conventional wisdom and shaped life as we know it Experiments have consistently been used in the hard sciences, but in recent decades social scientists have adopted the practice. Randomized trials have been used to design policies to increase educational attainment, lower crime rates, elevate employment rates, and improve living standards among the poor. This book tells the stories of radical researchers who have used experiments to overturn conventional wisdom. From finding the cure for scurvy to discovering what policies really improve literacy rates, Leigh shows how randomistas have shaped life as we know it. Written in a “Gladwell-esque” style, this book provides a fascinating account of key randomized control trial studies from across the globe and the challenges that randomistas have faced in getting their studies accepted and their findings implemented. In telling these stories, Leigh draws out key lessons learned and shows the most effective way to conduct these trials.

How to take advantage of technology, data, and the collective wisdom in our communities to design powerful solutions to contemporary problems The challenges societies face today, from inequality to climate change to systemic racism, cannot be solved with yesterday's toolkit. Solving Public Problems shows how readers can take advantage of digital technology, data, and the collective wisdom of our communities to design and deliver powerful solutions to contemporary problems. Offering a radical rethinking of the role of the public servant and the skills of the public workforce, this book is about the vast gap between failing public institutions and the huge number of public entrepreneurs doing extraordinary things--and how to close that gap. Drawing on lessons learned from decades of advising global leaders and from original interviews and surveys of thousands of public problem solvers, Beth Simone Noveck provides a practical guide for public servants, community leaders, students, and activists to become more effective, equitable, and inclusive leaders and repair our troubled, twenty-first-century world.

Randomised tests are carried out on us every day: by supermarkets, search engines, online dating sites, political parties and direct marketers. But how do these tests work? Are there any ethical issues? And what do they reveal about our choices? In Randomistas, Andrew Leigh tells the stories of radical researchers who overturned conventional wisdom in medicine, politics, business, law enforcement and more. From finding the cure to scurvy to discovering what policies really improve literacy rates, randomistas have shaped life as we know it – but they often had to fight to conduct their trials and have their findings implemented. “The subject of this book could hardly be more vital: are we humble enough to admit we may be wrong, and do we care enough to learn? Randomistas is rigorous, impassioned and tremendous fun. Everyone should read it." – Tim Harford, author of The Undercover Economist ‘A tour de force” – David Halpern,, author of Inside the Nudge Unit ‘Reveals how data and experiments can make the world a better place’ – Dean Karlan, professor of economics at Yale

The winners of the Nobel Prize in Economics upend the most common assumptions about how economics works in this gripping and disruptive portrait of how poor people actually live. Why do the poor borrow to save? Why do they miss out on free life-saving immunizations, but pay for unnecessary drugs? In Poor Economics, Abhijit V. Banerjee and Esther Duflo, two award-winning MIT professors, answer these questions based on years of field research from around the world. Called "marvelous, rewarding" by the Wall Street Journal, the book offers a radical rethinking of the economics of poverty and an intimate view of life on 99 cents a day. Poor Economics shows that creating a world without poverty begins with understanding the daily decisions facing the poor.

In October 2019, Abhijit Banerjee, Esther Duflo, and Michael Kremer jointly won the 51st Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel for their experimental approach to alleviating global poverty. But what is the exact scope of their experimental method, known as randomized control trials (RCTs)? Which sorts of questions are RCTs able to address and which do they fail to answer? The first of its kind, Randomized Control Trials in the Field of Development: A Critical Perspective provides answers to these questions, explaining how RCTs work, what they can achieve, why they sometimes fail, how they can be improved and why other methods are both useful and necessary. Bringing together leading specialists in the field from a range of backgrounds and disciplines (economics, econometrics, mathematics, statistics, political economy, socioeconomics, anthropology, philosophy, global health, epidemiology, and medicine), it presents a full and coherent picture of the main strengths and weaknesses of RCTs in the field of development. Looking beyond the epistemological, political, and ethical differences underlying many of the disagreements surrounding RCTs, it explores the implementation of RCTs on the ground, outside of their ideal theoretical conditions and reveals some unsuspected uses and effects, their disruptive potential, but also their political uses. The contributions uncover the implicit worldview that many RCTs draw on and disseminate, and probe the gap between the method's narrow scope and its success, while also proposing improvements and alternatives. Without disputing the contribution of RCTs to scientific knowledge, Randomized Control Trials in the Field of Development warns against the potential dangers of their excessive use, arguing that the best use for RCTs is not necessarily that which immediately springs to mind. Written in plain language, this book offers experts and laypeople alike a unique opportunity to come to an informed and reasoned judgement on RCTs and what they can bring to development.

How to get more innovation and more equality. Is economic inequality the price we pay for innovation? The amazing technological advances of the last two decades—in such areas as artificial intelligence, genetics, and materials—have benefited society collectively and rewarded innovators handsomely: we get cool smartphones and technology moguls become billionaires. This contributes to a growing wealth gap; in the United States; the wealth controlled by the top 0.1 percent of households equals that of the bottom ninety percent. Is this the inevitable cost of an innovation-driven economy? Economist Joshua Gans and policy maker Andrew Leigh make the case that pursuing innovation does not mean giving up on equality—precisely the opposite. In this book, they outline ways that society can become both more entrepreneurial and more egalitarian. All innovation entails uncertainty; there's no way to predict which new technologies will catch on. Therefore, Gans and Leigh argue, rather than betting on the future of particular professions, we should consider policies that embrace uncertainty and protect people from unfavorable outcomes. To this end, they suggest policies that promote both innovation and equality. If we encourage innovation in the right way, our future can look more like the cheerful techno-utopia of Star Trek than the dark techno-dystopia of The Terminator.

Why catastrophic risks are more dangerous than you think, and how populism makes them worse. Did you know that you’re more likely to die from a catastrophe than in a car crash? The odds that a typical US resident will die from a catastrophic event—for example, nuclear war, bioterrorism, or out-of-control artificial intelligence—have been estimated at 1 in 6. That’s fifteen times more likely than a fatal car crash and thirty-one times more likely than being murdered. In What’s the Worst That Could Happen?, Andrew Leigh looks at catastrophic risks and how to mitigate them, arguing provocatively that the rise of populist politics makes catastrophe more likely. Leigh explains that pervasive short-term thinking leaves us unprepared for long-term risks. Politicians sweat the small stuff—granular policy details of legislation and regulation—but rarely devote much attention to reducing long-term risks. Populist movements thrive on short-termism because they focus on their followers’ immediate grievances. Leigh argues that we should be long-termers: broaden our thinking and give big threats the attention and resources they need. Leigh outlines the biggest existential risks facing humanity and suggests remedies for them. He discusses pandemics, considering the possibility that the next virus will be more deadly than COVID-19; warns that unchecked climate change could render large swaths of the earth uninhabitable; describes the metamorphosis of the arms race from a fight into a chaotic brawl; and examines the dangers of runaway superintelligence. Moreover, Leigh points out, populism (and its crony, totalitarianism) not only exacerbates other dangers but is also a risk factor in itself, undermining the institutions of democracy as we watch.

From Nobel Prize–winning economist and New York Times bestselling author Robert Shiller, a groundbreaking account of how stories help drive economic events—and why financial panics can spread like epidemic viruses Stories people tell—about financial confidence or panic, housing booms, or Bitcoin—can go viral and powerfully affect economies, but such narratives have traditionally been ignored in economics and finance because they seem anecdotal and unscientific. In this groundbreaking book, Robert Shiller explains why we ignore these stories at our peril—and how we can begin to take them seriously. Using a rich array of examples and data, Shiller argues that studying popular stories that influence individual and collective economic behavior—what he calls "narrative economics"—may vastly improve our ability to predict, prepare for, and lessen the damage of financial crises and other major economic events. The result is nothing less than a new way to think about the economy, economic change, and economics. In a new preface, Shiller reflects on some of the challenges facing narrative economics, discusses the connection between disease epidemics and economic epidemics, and suggests why epidemiology may hold lessons for fighting economic contagions.

Is Australia fair enough? And why does inequality matter anyway? In Battlers and Billionaires, Andrew Leigh weaves together vivid anecdotes, interesting history and powerful statistics to tell the story of inequality in this country. This is economics writing at its best. From egalitarian beginnings, Australian inequality rose through the nineteenth century. Then we became more equal again, with inequality falling markedly from the 1920s to the 1970s. Now, inequality is returning to the heights of the 1920s. Leigh shows that while inequality can fuel growth, it also poses dangers to society. Too much inequality risks cleaving us into two Australias, occupying fundamentally separate worlds, with little contact between the haves and the have-nots. And the further apart the rungs on the ladder of opportunity, the harder it is for a kid born into poverty to enter the middle class. Battlers and Billionaires sheds fresh light on what makes Australia distinctive, and what it means to have – and keep – a fair go.

We’re all in this together. Strong social connections make communities more resilient. But today Australians have fewer close friends and local connections than in the past, and more of us say we have no-one to turn to in tough times. How can we turn this trend around? In Reconnected, Andrew Leigh and Nick Terrell look at some of the most successful community organisations and initiatives – from conversation groups to community gardens, from parkrun to Pub Choir – to discover what really works. They explore ways to encourage philanthropy and volunteering, describe how technology can be used effectively, and introduce us to remarkable and inspirational leaders. Reconnected is an essential guide for anyone interested in strengthening social ties. ‘Reconnected offers practical ideas, told through engaging stories of successful community-builders, about how to build a more connected Australia.’ —Robert D. Putnam, Professor of Public Policy at Harvard University and author of Bowling Alone and The Upswing ‘This inspiring collection of strategies and stories brings hope for the future. Reconnected shows that we are the revolution.’ —Dr Catherine Barrett, founder of The Kindness Pandemic
